Spot light electrical connection

I installed a spot light bar on a '92 Low Rider. The spots light, the running lights light but the directionals don't blink on and off. I can manually press the directional button and the light goes bright. The right indicator light stays on all the time. The left indicator light goes on and off when pressed.

I know I must have one of the wires mixed up. I thought I could save time asking someone which one it might be rather than digging through the nightmare of wires in the head light shell. And end up making even more trouble for myself.

Thanks
